A Data-Driven, Predictive Approach to Real-Time Optimization of Quality
Published on 2025-02-28 by Asif Ullah, Muhammad Younas, Mohd Shahneel Saharudin @MDPI
Abstract: In the ever-changing world of modern manufacturing, maintaining product quality is of great importance, yet extremely difficult due to complexities and the dynamic production paradigm. Currently, quality is rather reactively measured through periodic inspections and manual assessments. Traditional quality management systems (QMS), through these reactive measures, are often inefficient because of their higher operational cost and delayed defect detection and mitigation. The paper introduces a nov[...]
Our summary: A cognitive twin framework enhances quality management in flexible manufacturing systems through real-time data analysis and proactive decision-making, resulting in significant improvements in total quality scores, defects per unit, scrap rate, and overall equipment efficiency.

A Deep Semantic Segmentation Approach to Accurately Detect Seam Gap in Fixtured Workpiece Laser Welding
Published on 2025-02-20 by Fotios Panagiotis Basamakis, Dimosthenis Dimosthenopoulos, Angelos Christos Bavelos, George Michalos, Sotiris Makris @MDPI
Abstract: The recent technological advancements in today’s manufacturing industry have extended the quality control operations for welding processes. However, the realm of pre-welding inspection, which significantly influences the quality of the final products, remains relatively uncharted. To this end, this study proposes an innovative vision system designed to extract the seam gap width and centre between two components before welding and make informed decisions regarding the initiation of[...]
